<p>Check that the <code class="docutils literal notranslate"><span class="pre">LOGTALKHOME</span></code> and <code class="docutils literal notranslate"><span class="pre">LOGTALKUSER</span></code> environment
variables are defined, that the Logtalk user folder is available in
the location pointed by <code class="docutils literal notranslate"><span class="pre">LOGTALKUSER</span></code> (you can create this folder
by running the <code class="docutils literal notranslate"><span class="pre">logtalk_user_setup</span></code> shell script), and that the Prolog
compilers that you want to use are supported and available from the
system path. If the problem persists, run the shell script that
creates the integration script or shortcut manually and check for any
error message or additional instructions. For some Prolog compilers
such as XSB and Ciao, the first call of the integration script or
shortcut must be made by an administrator user. If you are using
Windows, make sure that any anti-virus or other security software
that you might have installed is not silently blocking some of the
installer tasks.</p>

<p>Changes in the Logtalk compiler between releases may render Prolog
adapter files from older versions incompatible with new ones. You may
need to update your local Logtalk user files by running e.g. the
<code class="docutils literal notranslate"><span class="pre">logtalk_user_setup</span></code> shell script. Check the <code class="docutils literal notranslate"><span class="pre">UPGRADING.md</span></code> file
on the root of the Logtalk installation directory and the release
notes for any incompatible changes to the adapter files.</p>
